Shirley Stafford Thagard, of Hayden Lake, was thinking happy thoughts of the show of force, with 500,000 of her closest friends, at the Women's March in Washington, D.C., as her plane approached Denver Monday. Then, the pilot pulled up from the runway and ascended again. He performed a 15-minute circle before successfully landing on a second try. Shirley found out why the pilot had performed the odd maneuver as she de-planed.
